SBECIELCA'EION forming part of Letters Patent No. 717,641, dated January 6, 1903.

Application filed December 6, .1901. Serial No. 84,928. (No model.)

Improvements in VVeather-Strips, of which the following is a specification.

This invention, which is mainly intended to a be applied to windows having sliding sashes and is designed to operate as a weatherstrip thereto, differs essentially from metal weather strips as ordinarily constructed, inasmuch as the strips will not bind the sashes in their seats when the framework or sash-bars become swollen or warped incident to dampness and changes in temperature, whereby and by its peculiar construction many advantages are seen red.

This invention consists in improved strips of metal adapted to be secured to the framework and sash-bars of a window and to engage with each other at their free ends, as hereinafter described.

Reference is to be had-to the accompanying drawings, forminga part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

In the drawings, Figure l is a horizontal cross-section of a side bar of the upper and a side bar of the lower sash of a window and of the jamb and stops in which the sash is seated. Fig. 2 is a perspective of an end of the weather-strip used on the jamb A. Fig. 3 is a perspective of an end of. the weather-strip used on the upper and lower sash bars.

In Fig. 1, A indicates the side jamb of a window. 13 indicates the parting-strip that extends upright between the two grooves or tracks that the sashes run in. 0 indicates the sash-stop at the inside of the jamb. D indicates the blind-stop. 02 indicates a side rail of the lower sash, and b indicates a side rail of'the upper sash. The blind-stop extends inward from the jamb A. The parting-strip B is set in a groove in the jamb A and projects from the jarnb', extending outward from the face thereof. The sash-stop C is set on the jamb A, and there is thus formed between the blind-stop D and the parting-strip B a'vertical groove extending from the top to the bottom of the frame, and this groove constitutes the way or track that the upper sash travels in, and there is also formed between the parting-strip B and the sash-stop C a similar vertical groove which constitutes the way or track for the lower sash.

The weather-strip E is made of a strip or band of sheet metal or other suitable substance and is secured to the jamb Anear the edge E The edge E thus is in a measure resilient by being fixed at but one point in.

its breadth, and is thus able to accommodate itself to The irregularities of movement of the sash. The strip E extends along and over the face of the jamb A in the grooves or tracks in which the sash-bars run and in such a way as to form a narrow passage-way between the face of the edge E and the stop or parting-strip facing said edge.

The weather-strip F is made, preferably, of sheet metal turned lengthwise at an angle to itself to form the flanges F and F The sash-bar a b is provided with a shallow rabbet g, that is out along and inward on the plane of said sash-bar and registering with the outer edge thereof. The flange F of the strip F is secured to the plane of the sashbar and in the rabhet g, the flange F extending beyond the outer edge of the sash-bar and inward to form the narrow groove or passage-way H between itself and said sash.- bar.

In operation the free end of strip E glides smoothly and noiselessly between the flange F of strip F and the sash-bar and when the window is closed efiectually prevents the dust and air-currents from passing around the sash-bars to which they are attached. In the drawings the strip E is shown as applied to a window with a thin lath of wood upon the jamb A; but this may not be always found necessary in actual practice, as the flange F will glide smoothly on the face of the jamb, and the strip E being flexible will accommodate itself. Both strips are secured to their respective parts by means of nails or screws.

It will be seen'by reason of the flexibility of the strip E and the depth of the groove or passage-way H that these strips will not cause the sashes to bind in their seats when afiected by the weather.

Having thus described myinventiomwhat I claim as new is 1. In a window, the combination of a casing provided with grooves or tracks, a sash adapted to move within said grooves or tracks, angle-shaped strips secured in rabbets on the sides of the sash-frames and extending over the outer portions of the same, and means consisting of strips located in said grooves or tracks and extending between the angleshaped strips and the sash, substantially as and for the purposes set forth.

2. In a window, the combination of a casing provided with grooves or tracks, a sash adapted to move within said grooves or tracks, angle-shaped strips secured to said sash, and unbent flat strips located in said grooves or tracks and forming bearing-surfaces for said the presence of two subscribing witnesses,
